Graham, a Republican who serves on the Senate Armed Services Committee, was addressing the South Carolina Republican Party’s annual Silver Elephant fundraising dinner. He mentioned the attack in passing, amid a longer discourse on U.S. national security policy.

Israeli officials on Saturday confirmed the strike was targeting a shipment of advanced missiles bound for the Lebanese militant group Hezbollah, the Associated Press reported.

Graham charged the Obama administration with weakening the United States as an international power and failing to support Israel adequately as an ally against “radical Islam” in general, and Iran specifically.

“If we do not stop this radical regime in Iran from acquiring a nuclear weapon, we’re gonna be on the road to Armageddon,” Graham said.

Graham’s remarks on Syria came after CNN Pentagon correspondent Barbara Starr reported on Twitter: “US and western intel agencies looking at new info showing Israel conducted airstrikes against Syria target.”

A spokesman for Graham did not immediately return an email seeking to clarify whether Graham was referring to Starr’s report, or his own independent information.

President Barack Obama said earlier this week that indications Syria may have used chemical weapons against its own people would prompt the United States to consider new, lethal options for responding to mass bloodshed in the Mideast dictatorship.

In addition to his remarks on Syria, Iran and South Carolina politics, Graham said that current American counterterrorism policy was ineffective at preventing last month’s bombings in Boston. He called for empowering the federal government to monitor people who look at radical Islamic websites, and deplored that Boston bomber Tamerlan Tsarnaev was allowed to visit Russia after his family sought refuge in the United States.

“We’re gonna fix that in the immigration bill. If you get asylum, you ain’t going back,” Graham pledged.
